SPECTROPHOTOMETRIC DETERMINATION OF PARACETAMOL USING ZIRCONIUM (IV) OXIDE AND AMMONIUM TRIOXOVANADATE (V)
ABSTRACT A simple and sensitive spectrophotometric method for the determination of paracetamol was explored, using zirconium(IV) and vanadium(V) oxides. The method was based on the oxidation of paracetamol by zirconium(IV) and vanadium(V) m alkaline and acidic media respectively. The stoichiometric studies indicated a mole-ratio of 1: 1 for the reactions of paracetamol with both zirconium(IV) and vanadium(V). Effects of other variables like pH, temperature and time were determined and showed ...
